UNITE STATES PATENT OFFICE.

THOMAS COLDWELL, OF NEWBURG, NEW YORK.

BRUSH-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 294,583, dated March l,1884.

Application filed November 3,1853. (N model.)

.To all whom it may concern.-

Be it known that I, THOMAS OoLDwELL, of Newburg, in the county ofOrange, and in the State of New York, have invented certain new anduseful Improvements in Machines for Trimming Brushes; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, making a partof this I I0 specification, in which- Figure l is a perspective view ofmy machine as arranged for use. Fig. 2 is a plan View of the upper sideof the same. Fig. 3 is a side elevation, partly in section, and Fig. 4

I 5 is a perspective viewof the rotary cutter.

2o draw the center row of knots of bristles. into the wood; then, bymeans of hand-shears provided with a gage, to cut off the ends of thebristles, so as to reduce the latter to a uniform length. The nextadjacent rowofknots was then drawn into the wood and trimmed, and

such operation repeated until all of the bristles were in place andtrimmed, completing such portion of the'brush. In the trimming ofbrushes, as stated, the wood forms the gage, and'the 3o ends of thebristles must conform to the shape of said wood, so that if the latteris fiat said. bristles cannot be trimmed circular or oval, as would bedesirable in many instances.

. To obviate these objections, and to enable brushes to be easily,quickly, and perfectly trimmed to any desired shape, and at a smallcost, is the design of my invention, which in-- vention consists in theslides or trimming-gages 1 constructed and adapted to operate in theman- 40 ner and for the purpose-substantially as hereinafter shown anddescribed.

It consists, further, in the means employed for adjusting to andsecuring in vertical position the slides or trimming-gages,substantially as and for the purpose hereinafter specified.

It consists, finally, in the machine as a whole, its several parts beingconstructed and combined to operate in the manner and for the purposesu-bstantially as hereinafter shown.

In the annexed drawings, A represents the base-plate of my machine,which has a general rectangular form with an open center, and

rests upon and is supported by legs B, that have such length as to causesaid plate tooccupy a convenient position for use.

Journaled within suitable boxes 0, upon the upper side of the plate A,is a shaft, D, which, between said boxes, is enlarged to form a hub, d,and at equidistant points around the periphery of such hub is providedwith radial blades (1, which are arranged in two series, each of whichextends from one end of said hub longitudinally inward to or beyond thecenter of the same. The blades 01 of one series are arranged so thattheir inner ends come opposite to or are contained within the spacesbetween the ends of the opposite series. Each of said blades is formedlongitudinally upon a straight line, and those of one series arearranged upon lines which are relatively opposite to the lines of theblades of the adjacent series.

Extending upward from the base-plate A are two lugs, E, which arelocated in front of the boxes 0, and at such distance apart as to enablethe cutter-blades d to pass freely between as said cutter revolves. Afiat bar or plate, F, having the rectangular form shown in Fig. 2,extends horizontally over the upper ends of said lugs, and is connectedtherewith by means of four screws, G, two of which screws pass downwardthrough each end of said bar, with their heads above the latter andtheir threaded ends contained within correspondingly-threaded openingsin said lugs. A third screw, H, passing downward througlzg. a threadedopening in each end of the bar F,

end in contact with the upper end of the lug E, operates to limit thedownward motionv of said bar, while said screws G operate to hold thelatter firmly at such limit. By the proper manipulation of said screwsthe vertical posiward throughan ear,'c,-which extends up midway betweenthe screws G, with its lower blades, slides for supporting and guidin aIn testimony that I claim the foregoing I brush while'beingtrimmed, andmeans, subhave hereunto set my hand this 16th day of stantially asshown, for adjusting said slides October, A.
